BUILDING-LIGHT.

Specification of Letters Patent. Application filed August 2, 1907.

Patented June 2, 190s.

semi No. 386,188.

To all whom it may concern: l

Be it known that I, PHILIP SoiiwioKAn'r, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented ,a new and Improved Building-Light, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and im ioved building light for use on vaults, sky lights, floors, etc., and which is completely water and moisture-proof, and arranged to distribute the rays of light uniformly over a large space, and to permit of conveniently placing the lights in position in the supporting frame and securely locking the same therein.

rPhe invention consists of novel features and parts and combinations of the same, which will be more fully described hereinafter and then ointed out in the claims.

A practica embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

`Figure l is a plan view of the improvement; parts being broken out Fig. 2 is a sectional side elevation of the same on the line 2-2 of Fig. 1, and Fig. 3 is a cross section of the same, on the line 3-3 of Fig. 1.

The metallic main frame or support A is preferably formed of front and rear bars A', A2, integrally connected with each other by spaced cross bars A3 of T-shape, and having cut out ortions A4L adjacent to the front bar A2, to allow of conveniently placing the glass lights or prisms B in position on the said plained.

Each of the Olass lights or prisms B consists of a conical top or upper portion B and a lower portion B2 of pyramidal shape, the upper end of the lower portions B2 fitting between the adjacent cross bars A3 and forming with the base of the upper conical portion shoulders B3 adapted to rest on the adjacent crossbars A3, as plainly indicated in Figs. l and 3.

The bases of the lower portions B2 of the glass lights B project below the bars A3 of the frame A and are preferably square, andthe the other, so that the bottom surface of the structure is of glass of unbroken continuity.

The conical top portions B of the glass lights B are provided with annular shoulders or beads B4 adapted to rest at the front and rear on sup orting bars C laid on top of the frame A an extending at right angles to the bars A3, so that each glass light B is supported on the sides by the bars A3, and at the front and rear by the bars C. The bars Care preferably of inverted T-shape (see Fig. 3) and rest loosely on top of the main frame A.

The corners B5 of the lower portion B2 of each glass light B are chamfered, to permit cement or a similar plastic binding substance D to pass down between the adjacent bars C and A3, with a view to completely embed the cross bars A3, and to fill the spaces between the sides of the glass lights B.

The lower portion B2 of each glass light B is preferably provided with a recess B, the top B7 of which may be conical or ornamented, if desired.

In placing the building light in position, the main frame A is first set in place and then the glass lights B are introduced from the bottom upward throughithe cut-out portions A2, which are sufficiently large to permit the conical portion Bl of each glass light B. The glass light B is now slipped forward between adjacent bars A3 with the shoulder B3 resting on top of the adjacent bars A3, and in a similar manner theseveral glass lights are introduced and pushed in lace, one alongside the other, so that the si es of the square bases fit one against the other, to produce an entire surface of glass of unbroken continuity. When the lights have been placed in position on the main frame A, the bars C can be pushed in from the ends of the main frame A, and then the cement or other polastic binding substance D is poured down etween adjacent lights, so that the cement completely fills the spaces between the adjacent lights B, and at the same time completely embeds both the supporting bars A3 and C.

By the arrangement described an exceedingly strong and durable building light is produced, which is completely water and moisture-proof, and by its unbroken glass surface at the bottom is capable of distributing the rays of light uniformly and over a sides of the adjacent bases abut one against l large area.

The building light shown and described can be cheaply manufactured and quickly set up, and used for various purposes such as covers for vaults, sky lights, lloors and the like.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1. A building light, comprising a support formed of sets of superimposed spaced bars at right angles one to the other, glass lights having shoulders for engaging each set of bars, and a plastic binding material filling the spaces between the glass lights embedding tie said bars.

2. A building light, comprising a support, glass lights having square lower ends sup` ported on the said support and projecting above and below the same, said square ends contacting with the adjacent lights to form a continuous glass surface and a binding material in which the support is completely embedded and which iills the spaces between the sides of the lights.

3. A glass light having a conical upper portion and a s uare bottom portion, forming with the said upper portion, a supporting shoulder, and a second supporting shoulder on the conical upper portion.

4. A glass light having a conical upper portion and a square bottom portion, forming with the said upper portion a supporting shoulder, and a second supporting shoulder on the conical upper portion, the corners of the square bottom portions being chainfered.

5. A glass light having a conical upper portion and a square bottom portion, forming with the said upper portion .a supporting shoulder, and a second supporting shoulder on the conical upper portion, the corners of the square bottom portions being chamfered and the under side of the bottom portion being recessed.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
